Using NDT to Reduce Traffic Delays in Concrete Paving

Fast track paving has centered on the use of construction materials and methods to improve the rate of placement and curing to reduce the traffic delay time. The State of Iowa has been able to make large improvements in the fast track process to meet target traffic delay constraints through material selection and construction methods. At the same time the methods for monitoring concrete strength gain and quality have not changed. In 1995, Lee county and the Iowa DOT cooperated through research project, HR-380, to construct a 7.1 mile project to demonstrate the use of maturity and pulse velocity nondestructive testing methods to estimate concrete strength gain and reduce traffic delay. The results of that work identified the pros and cons of each method and suggested specifications to meet traffic delay demands. The results also identified examples of equipment that could easily be used by project personnel to estimate the concrete strength using the maturity methods.
